#6 Tank Welding Bung

The #6 Tank Welding Bung from AEROQUIP is a precision-engineered weld-on port adapter designed for fuel systems, hydraulic tanks, and fluid transfer applications requiring permanent, leak-proof connections. Built for professionals and serious enthusiasts who demand reliability in high-pressure environments, this welding bung provides a secure female AN connection point that eliminates the need for threaded fittings where vibration or system pressures would otherwise compromise joint integrity. The weld-on design ensures a structural bond between the bung and tank, making it ideal for custom fabrication, racing fuel cells, aerospace components, and industrial hydraulic systems.

This #6 AN female welding bung features a 1.56-inch diameter mounting flange with a 0.68-inch thickness, offering substantial contact area for a strong, durable weld bead. Manufactured from aluminum in its natural finish, the bung resists corrosion while remaining lightweight—critical for performance and racing applications where every pound matters. The 6 AN female port accommodates standard -6 AN hose and fittings, ensuring compatibility with industry-standard quick disconnects, fuel lines, and hydraulic assemblies. Its compact overall dimensions (2.25 x 1.1 x 3.7 inches) allow installation in tight engine bays and tank configurations without excessive protrusion or interference with surrounding components.

Professionals in custom fabrication, motorsports, and industrial fluid power systems rely on the #6 Tank Welding Bung for permanent tank ports where bolted or threaded connections would fail under vibration or pressure cycling. Installation requires TIG or MIG welding to the tank wall; proper surface preparation and qualified welding technique ensure a leak-free, structurally sound result. This bung is ideal for fuel cell construction, vintage vehicle restoration, competition racing applications, and any scenario demanding a non-removable, maintenance-free connection. Whether you're building a high-performance fuel system or upgrading hydraulic infrastructure, AEROQUIP's proven design delivers the durability and safety required for demanding environments.
